Detailed Description
The technical solution of the present patent application will be described in detail below, but the scope of protection of the present patent is not limited to the specific implementation structure.
The utility model provides an automatic safety protection system device of conflagration of passenger train electrical system, including fire extinguishing control part 5, fire extinguishing terminal 4 and response terminal in this system, still include early warning outage control part 6, electrical apparatus and engine total control part 8 and outage terminal 7.
The induction terminal comprises a temperature induction part 1, a smoke inductor 2 and a thermosensitive wire 3, wherein a plurality of induction devices are distributed in working areas of key electrical appliances such as a battery compartment, a high-voltage electrical appliance compartment, a motor compartment or a power distribution compartment, and are used for inducing the working temperature of the sensitive area, whether smoke exists or not, and abnormal conditions such as open fire occur.
The fire extinguishing control part 5 is used as a device for open fire induction protection, an acquisition bus channel of the fire extinguishing control part is connected with the induction terminal, and the key point is that the fire extinguishing control part is connected with the thermosensitive wire 3, and an execution bus channel of the fire extinguishing control part is connected with the fire extinguishing terminal 4.
The early warning power-off control part 6 is respectively communicated with the electric appliance and engine master control part 8 and the fire extinguishing control part 5, and the electric appliance and engine master control part 8 is provided with an execution channel for adjusting the current of a driving motor or the fuel injection quantity of an engine.
In this embodiment, the early warning power-off control portion 6 is also provided with an induction collection bus channel, and the temperature sensor 1 and the smoke sensor 2 in the induction terminal are connected with the early warning power-off control portion 6 through the collection bus channel to monitor the working temperature of each sensitive area and the existence of abnormal smoke conditions.
